ISO 15745-5:2007

Overview

ISO 15745-5:2007 is an international standard published by the International Organization for Standardization (ISO) that specifies the technology-specific elements and rules for describing communication network profiles and device profile communication aspects in HDLC-based control systems. Serving as Part 5 of the ISO 15745 series, it is designed for industries utilizing High-level Data Link Control (HDLC) protocols, such as CC-Link systems, to promote interoperability and integration in industrial automation environments. This standard operates in conjunction with ISO 15745-1, which defines the generic elements and rules for an application integration framework (AIF) applicable to various communication technologies.

Key Topics

• HDLC-Based Control Systems: Focuses on standardizing device and communication network profiles for automation systems using the HDLC protocol (also referenced as ISO/IEC 13239).
• Profile Templates: Provides XML schema-based templates to describe both communication networks and device profiles, ensuring compatibility and easy data exchange between automation components.
• Legacy Compatibility: Includes mechanisms to encapsulate legacy ASCII-based CC-Link System Profile (CSP) files using XML wrappers, enabling continued use of existing configurations and investment protection.
• Device Profile Structure: Outlines key elements such as Device Identity, Device Manager, Device Function, and Application Process, which collectively provide a detailed and structured data representation.
• Communication Network Profile: Defines core elements to describe the application layers, transport layers, and network management specific to CC-Link, covering both cyclic and extended cyclic operations as well as transient messaging.
• XML-Based Schemas: Emphasizes the use of XML (Extensible Markup Language) and related W3C standards (such as XML Schema and UML), ensuring profiles are machine-readable and interoperable.
• Vendor and Technology Neutrality: While supporting CC-Link terminology, ISO 15745-5:2007 enables configuration for any HDLC-based control system, supporting a broad range of device and vendor implementations.

Applications

• Industrial Automation System Configuration: Simplifies integration and configuration for HDLC-based networks, including CC-Link devices, by providing standardized templates and data representations.
• Interoperability and Integration: Facilitates the seamless exchange of information between devices and software tools from different manufacturers, improving scalability, maintainability, and flexibility of automation systems.
• Legacy System Modernization: Supports encapsulation and migration of legacy ASCII CSP files into modern XML formats, aiding industries in evolving their automation infrastructure without losing historical configurations.
• Automated Device Management: Enables software tools to automatically identify, configure, and manage devices using the standardized profiles, reducing manual intervention and error.
• Compliance and Procurement: Provides a uniform framework that aids in the verification of device capabilities, simplifying procurement, compliance checks, and system certification in complex automation setups.
